Each tGard stack has between one and ten slots for different elements which create an interlock that is configured for your specific application. Each slot can have a mix of different things, this page gives technical details about Safety & Access Key.
If you are not familiar with tGard we recommend you first read about the range in general on the tGard product page or look at our how to buy tGard page to understand the process of configuring the perfect stack.
